As the snow cover is finally melting and we hit nearly 50 degrees, I spotted my first crocus of the season. Not surprisingly, it has exposure to the southern winter sun and is near a concrete foundation — which both provides thermal mass and conducts warmth down into the soil.
I'm also not surprised that it's yellow. Crocus flavus, a yellow species from Greece and Turkey is often included in C. vernus mixtures, in which C. flavus 'Golden Yellow' blooms before the purple and white selections.
My first crocus sighting this year, in the Briarwood section of Queens.
